`(y-x)(y+x)` is equal to:

If log(x-y)-log5-(1)/(2)log x-(1)/(2)log y=0 then (x)/(y)+(y)/(x) is equal to

If x>=y>1 then the maximum value of log_(x)((x)/(y))+log_(y)((y)/(x)) is equal to

if (x)/(y)=(3)/(2) then (x+y)/(x-y) is equal to:

If x,y and z are pth,>h and rth terms respectively of an A.P and also of a G.P. then x^(y-z)*y^(z-x)*z^(x-y) is equal to

The value of ((x-y)^(3)+(y-z)^(3)+(z-x)^(3))/(9(x-y)(y-z)(z-x)) is equal to (a)0(b)(1)/(9)(c)(1)/(3)(d)1

The value of ( x-y ) ( x + y ) + ( y -z ) ( y + z ) + (z-x ) (z + x ) is equal to

If x ,y ,a n dz are pth, qth, and rth terms, respectively, of an A.P. nd also of a G.P., then x^(y-z)y^(z-x)z^(x-y) is equal to a.x y z b. 0 c. 1 d. none of these
